[mpich-discuss] Running MPIEXEC on Windows 7

[Jayesh Krishna]

Hi,
 This seems to be a problem with the MPICH2 installation (Although you are not getting any error messages it looks like the process manager was not installed correctly).
 Uninstall your existing version of MPICH2. Please follow the instructions in the MPICH2 installer's guide (http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=docs - Section 9.4) to install MPICH2 (Don't follow instructions in 9.1).
 Let us know if it works for you.

Regards,
Jayesh

Subject: [mpich-discuss] Running MPIEXEC on Windows 7


I have been successfully running all my parallel codes on Windows NT. I've had one computer converted to Windows 7 and cannot get mpiexec to run even the simple cpi example. My command in an Adminstrator MS-DOS prompt is: 

mpiexec -n 4 cpi 

I get back the following error: 

Error while connecting to host, No connection could be made because the target machine actively refused it. (10061) 
Connect on sock (host=igswcawwws1889.gs.doi.net, port=8676) failed, exhaused all end points 
Unable to connect to 'igswcawwws1889.gs.doi.net:8676', 
sock error: Error = -1 


I've also run it using wmpiexec and get the same result. I've allow mpiexec and cpi to run under the Windows firewall so I'm not sure what to look for in Windows 7. 

Thanks. 

Alan
